Problems solved by technology
If you need to research or verify new data processing algorithms, you need to write a program (such as MATLAB language, etc.) for verification, and it has not been written in one step into a C language or C++ language format that can be executed by a digital signal processor (DSP). , which means that the off-line data processing of the radar seeker without data analysis software such as MATLAB will be difficult to achieve

Embodiment Construction
[0033] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0034] The present invention includes signal processing and data processing algorithms and a set of self-compiled simulation analysis software, radar signal data collector, control computer and radar seeker with optical fiber communication, such as figure 2 For its hardware connection diagram, the simulation analysis software can be regarded as the softwareization of the signal processor, which can simulate the functions of the signal processor, such as executing algorithms and data processing. In this method, when the radar echo signal is processed, the data acquisition equipment is used to collect the summation / difference signal after down-conversion processing from the optical fiber interface of the seeker signal processor at high speed and save it on the data acquisition equipment, and then pass The network cable imports the collected data to the control com...

The invention relates to a radar seeker signal processing simulated analysis method and system. A data collector collects sum and difference signals, after down conversion by a radar receiver, at a high speed via an optical port of a seeker signal processor, and stores the sum and difference signals, the collected data is introduced into a control computer via a network cable, corresponding signal processing simulated analysis is carried out, and a processing result is reflected in the data and figure forms. Thus, the system can analyze the seeker data needless of purely relying on original MATLAB simulation analysis software and the like, and C++ language based self-programmed processing algorithms of the system can be transplanted to DSP and implemented, and the DSP algorithm can be improved and verified.
Description
technical field [0001] The invention relates to the field of radar seeker signal processing and data processing, in particular to a radar seeker signal processing and data processing simulation analysis method. Background technique [0002] In the development stage of the radar seeker, a large number of signal processing and data processing simulation analysis work is required to verify the performance of the algorithm or locate the fault location. When conducting seeker field tests, in order to better analyze target characteristics or find hardware problems, it is necessary to conduct a comprehensive and in-depth analysis of the seeker echo data, which cannot be accomplished using the seeker's own hardware and software Work can only be done by collecting seeker echo data, and then using simulation analysis software for offline analysis of these actual data. [0003] For off-line analysis of seeker data, the data collector is often used to collect the IF echo data after the...
